Homebrew
Evasion. When the tenome is subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.
Keen Hearing & Smell. The tenome has advantage on Wisdom (Perception) checks that rely on hearing or smell.
Turn Resistance. The tenome has advantage on any saving throws against any effect that turns undead.
Multiattack. The tenome makes three Slam attacks.
Slam. Weapon Melee Attack: +4 to hit, reach 5', one target. Hit: 9 (2d6 + 2) bludgeoning damage.
Bone Drain. The tenome can touch one creature that is willing, grappled by the tenome, incapacitated, or restrained. It then uses its necrotic powers to attempt to liquify & absorb the target's bones. The target must succeed on a DC 12 Constitution saving throw or take 5 (1d6 + 2) necrotic damage & have their Constitution score lowered by 2 (1d4). On a success, the target only suffers the necrotic damage. For each point of the target's Constitution score that is lowered with this feature, the tenome gains 5 temporary hit points.
If the targeted creature's Constitution score reaches 0 due to this feature, the targeted creature dies with its entire skeleton being liquified & absorbed by the tenome. The targeted creature's body will reanimate as a Boneless in 3 (1d6) days. If the creature is to be resurrected, it must first have its skeleton restored by casting the Regenerate spell or similiar magic.
Aggressive. The tenome can move up to its speed toward a hostile creature that it can see.
Beggar's Embrace. If the tenome successfully hits a target with a Slam attack as an Action or Reaction, then it can attempt to grapple the target.
